Workers with the Canadian energy company Suncor unearthed ankylosaur remains while mining oil sands near Fort McMurray in Alberta. The carcass of the four-legged land creature was not flattened, as is the case with many fossilized vertebrates. But most strangely, it was found in an area known primarily for fossilized marine creatures.

Algal cells and cell parts are known to live inside the cells of an array of sea creatures, including certain sea slugs and jellyfish.¹ Over 100 years ago, algae were found in association with certain salamander eggs, but their mode of living remained mysterious.

NASA recently released the most detailed images yet of the "far" side of the moon, or the side that faces away from earth.¹ The Lunar Reconnaissance Orbiter took thousands of images that were assembled into a mosaic of the lunar surface. Both the moon's far and near sides contain craters, which may hold clues to its history.

Teeth and fossil bone fragments from a meat-eating T. rex-like dinosaur were discovered in a Chinese dinosaur bone bed. The remains indicate that the creature measured over 30 feet from nose to tail.¹ How did such a large creature come to be fossilized alongside so many other dinosaurs?
